Radcliffe's Dagger Moth
Acronicta radcliffei

Observation date: August 09, 2025
Submitted by: Ozark_Bill
Specimen type: Photograph
Observation notes: Found on cherry (Prunus serotina)
Status: Resident
Verified by: Ozark_Bill
Verified date: August 10, 2025
Coordinator notes: There have been no confirmed collections of A. superans in MO, per Heitzman's catalogue. The larva of A. superans looks quite similar to the penultimate instar of A. radcliffei. The primary differences are that A superans will have black snowflaking on the head, whereas A. radcliffei will have this patterning in red. Another potential option is A. hasta, but I think less likely. All three are cherry/rose specialists
